Couldn’t agree more, there should definitely be Voyagers from Avanti added to the fleet to replace them.
As for the first class seats being the best, I could never afford one so can’t comment.

I seem to remember first class being an Orange/brown and standard (second as it was called then) was all blue. Happy times travelling up and down the country on them.
Obviously I’d rather they were retained but if it satisfies the cuts that Have been imposed on them then there could have been worse outcomes (and probably will be in the next round of cuts )
